Walk through the Amazon rainforest today and you will find it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same ?For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted(反应)to the cold ,dry climates of the ice ages ,but until now ,no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming . Currently the trees in the Amazon take in around 500 million tons of CO2 each year; equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier ,will it still survive and continue to draw down CO2 ?Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.
Unfortunately ,getting into the Amazon rainforest and collecting information are very difficult .To study past climate ,scientists need to look at fossilized pollen ,kept in lake muds .Going back to the last ice age means drilling deep down into lake sediments (沉淀 物),which requires specialized equipment and heavy machinery .There are very few roads and paths ,or places to land helicopters and aeroplanes .Rivers tend to be the easiest way to enter the forest ,but this still leaves vast areas between the rivers completely unsampled(未取样).So far ,only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.
64.The underlined phrase “mopping up” in the second paragraph means .
A.cleaning up B.taking in C.wiping out D.giving out
65.How will the Amazon rainforest react to future climate change?
A.It’ll get drier and continue to remove CO2 .
B.It’ll remain steamy ,warm ,damp and thick .
C.It’ll get warmer and then colder and drier.
D.There is no exact answer up to present.
66.What’s the main idea of the last paragraph?
A.It’s important to drill deep down into lake sediments to collect information.
B.It’s impossible to prove how climate changes in the Amazon rainforest.
C.It’s hard to collect information for studies of the past climate in the Amazon rainforest.

We were on tour a few summers ago, driving through Chicago, when right outside of the city, we got pulled over. A middle-aged policeman came up to the car and was really being troublesome at first. Lecturing us, he said, "You were speeding. Where are you going in such a hurry?" Our guitarist, Tim, told him that we were on our way to Wisconsin to play a show. His way towards us totally changed. He asked, "Oh, so you boys are in a band (乐队)?" We told him that we were. He then asked all the usual broad questions about the type of music we played, and how long we had been at it. Suddenly, he stopped and said, "Tim, you want to get out of this ticket, don't you?" Tim said, "Yes." So the officer asked him to step out of the car. The rest of us, inside the car, didn't know what to think as we watched the policeman talk to Tim. Next thing we knew, the policeman was putting Tim in the back of the police car he had parked in front of us. With that, he threw the car into reverse(倒车), stopping a few feet in back of our car. Now we suddenly felt frightened. We didn't know if we were all going to prison, or if the policeman was going to sell Tim on the black market or something. All of a sudden, the pollen's voice came over in a loudspeaker. He said, "Ladies and gentlemen, for the first time ever, we have Tim here singing on Route 90.” Turns out, the policeman had told Tim that the only way he was getting out of the ticket was if he sang part of one of our songs over the loudspeaker in the police car. Seconds later, Tim started screaming into the receiver. The policeman enjoyed the performance, and sent us on our way without a ticket.The policeman stopped the boys to ______.

Do you want to be a successful person? Would you like to know how successful people usually think and what drives them? Here I am going to tell you the key to success that successful people share.
First of all, successful people never blame someone or something outside of themselves for their failure to move ahead. They realize that their future lies in their own hands. They understand that they can’t control things in life, such as nature, the past and other people. At the same time, they are well aware that they can control their own thoughts and actions. They take responsibility for their life.
Perhaps what most separates successful people from others is that they live life “on purpose”-- they are doing what they believe they are put here to do. In their opinion, having a purpose in their life is the most important element that enables them to deal with things around them. They hold the view that when they live their life “on purpose”, their main concern is to do the job right. They live what they do. People want to do business with them because of their commitment. To live their life “on purpose”, successful people find a cause they believe in and create a business around it.
Besides, they never give up easily. Once they have set up goals in their life, they are willing to do whatever it takes to achieve their goals. To achievers always bear in mind what they don’t have forever. Rather than see this as negative or depressing, they would use the knowledge to spur themselves on and go after what they want energetically and passionately.
So keep in mind what successful people always hold to be true so that you will have a clear idea of what you should do to be successful in life.According to the passage, to be successful, ______.
A.you should set up a realistic goal |
B.you should know your strengths and weaknesses |
C.you shouldn’t blame others for your failure |
D.you shouldn’t waste time |
Which is NOT the key to success that successful people share?
A.Taking responsibility for their life. |
B.Never giving up easily. |
C.Having a goal in life. |
D.Controlling things in life. |
The underlined word “spur” in paragraph 4 probably means “______”.
A.interest | B.equip |
C.depend | D.inspire |
The author’s purpose in writing this passage is to ______.
A.explain the exact meaning of success |
B.share the key to success with readers |
C.tell his experience of achieving success |
D.encourage readers to learn from failure |

It was Monday, Mrs. Smith’s dog was hungry, but there was not any meat in the house.
Considering that there was no better way, Mrs. Smith took a piece of paper, and wrote the following words on it: “Give my dog half a pound of meat.” Then she gave the paper to her dog and said gently: “Take this to the butcher(卖肉者), and he’s going to give you your lunch today.”
Holding the piece of paper in its mouth, the dog ran to the butcher’s shop. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady’s handwriting and presently did as he was asked to. The dog was very happy, and ate the meat up immediately.
At midday, the dog came to the shop again. It gave the butcher a piece of paper again. After reading it, he gave it half a pound of meat once more.
The next day, the dog came again exactly at midday. And as usual, it brought a piece of paper in the mouth. This time, the butcher did not take a look at the paper, and gave the dog its meat, for he had thought of the dog as one of his customers.
However, the dog came again at four o’clock. And the same thing happened once again. To the butcher’s more surprise, it came for the third time at six o’clock, and brought with it a third piece of paper. The butcher felt a bit puzzled. He said to himself, “This is a small dog. Why does Mrs. Smith give it so much meat to eat today?”

B.a piece of paper could bring him half a pound of meat |
